Abstract
The utility model discloses a carbon fiber pipe which comprises a cylindrical pipe body, wherein the pipe body is a carbon fiber pipe body, a metal inner wall is arranged on the inner side of the pipe body, and a plurality of helical line strengthening convex ribs are arranged on the outer side of the pipe body, are mutually parallel and are uniformly distributed at equal intervals. The carbon fiber pipe has the benefits that the strengthening effects of the helical line strengthening convex ribs are better than those of straight strengthening ribs, so that the strength of the carbon fiber pipe is more improved; through the strengthening ribs with triangular cross sections, not only can the strengthening effects be realized, but also materials are saved, and meanwhile, the processing is convenient.
Description
Technical field
The utility model relates to a kind of composite material tube, is specifically related to a kind of carbon fiber pipe.
Background technology
Carbon fiber has the characteristics such as high strength, high-modulus, high temperature resistant, corrosion-resistant, endurance, creep resistant, conduction, heat transfer, belongs to typical new high-tech product.Aerospace, sports goods field, industrial circle, traffic and transport field and civil construction field have been widely used in.
In machining, also extensively adopt carbon fiber pipe alternative metals pipe at present, reach objects such as reducing machine own wt, raising intensity.But current carbon fiber pipe, reinforcement mostly is the reinforcement paralleling to the axis, and structure is single, and stiffening effect is general.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of stiffening effect better carbon fiber pipe.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of carbon fiber pipe, comprise columniform pipe shaft, it is characterized in that, above-mentioned pipe shaft is carbon fiber pipe shaft, above-mentioned pipe shaft inner side is provided with metal inner surface, above-mentioned pipe shaft outside is provided with many helixes and strengthens convex tendon, and many above-mentioned helixes are strengthened convex tendon and are parallel to each other, and every above-mentioned helix is strengthened convex tendon and is equidistantly uniformly distributed.
Further, the helical angle of above-mentioned helix reinforcement convex tendon is 45 ° ~ 60 °.
Further, the cross section of above-mentioned reinforcement convex tendon is triangle.
Further, the cross section of above-mentioned reinforcement convex tendon is isosceles triangle.
Further, the higher primary school of the cross section of every above-mentioned reinforcement convex tendon is in the length on base.
Usefulness of the present utility model is: helix reinforcement is better than the stiffening effect of the reinforcement of straight line, has more improved the intensity of carbon fiber pipe.Cross section is that leg-of-mutton reinforcement not only can play booster action but also saves material, simultaneously convenient processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model.
The implication of Reference numeral in figure:
10-pipe shaft, 11-metal inner surface, 12-reinforcement.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
A kind of carbon fiber pipe as shown in Figure 1 and Figure 2, comprise columniform pipe shaft 10, pipe shaft 10 is carbon fiber pipe shaft, pipe shaft 10 inner sides are provided with metal inner surface 11, pipe shaft 10 outsides are provided with many helixes and strengthen convex tendon 12, many helixes are strengthened convex tendon and are parallel to each other, and every helix is strengthened convex tendon 12 and is equidistantly uniformly distributed, and the distance between every helix reinforcement convex tendon 12 equals the helix reinforcement convex tendon 12 of 1.5 times to 2 times and the width of pipe shaft 10 contact positions.Metal inner surface 11 adopts aluminum pipe and carbon fiber pipe shaft to fit tightly.The quality of aluminium is light, and the carbon fiber pipe shaft in outside can be gained in strength.
The helical angle that helix is strengthened convex tendon 12 is 45 ° ~ 60 °.As shown in Figure 2, the cross section of helix reinforcement convex tendon 12 is triangle.As a kind of preferred version, the cross section that helix is strengthened convex tendon 12 is isosceles triangle, easy to process like this.
In order to guarantee that the height of helix reinforcement convex tendon 12 projections can be not too high, highly too high easy damage.Every helix is strengthened the higher primary school of cross section of convex tendon 12 in the length on base, and the intensity of the reinforcement convex tendon that the longer reinforcement convex tendon in base is shorter than base is high.Distance between every helix reinforcement convex tendon 12 is 2 ~ 3 times of base length.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
